Eye of Etlich and EB build

When I do solo T6 my gear will be just like in my profile, thanks to the help of double Unity. But when I do public game, when I swap my Unity for SoJ, each range damage I got will be so painful. So, I'll put on my Eye of Etlich that has stat like following

Primary745 Int << Reroll+10% CC96 AR+20% Fire Damage

Secondary-32 % Range Damage-7% % Melee Damage

Problem is, it doesnt' have +CHD so my Chain Reaction blast will be around 6-7m to white while the current setup in my profile do 7.5-8.5m to white.

I'm trying to reroll Int to CHD for more than 35m already but the best I got was +63% CHD so I always stayed with Int.

Question is, since I never successfully reroll int to high CHD before, is it worth keep trying to get > 85% CHD or not? will thare be significant different between 745 Int and > 85% CHD?
